To ZZ whom' 't muy cmwcrn:

Be it known that l, (Kimi J. LANuix, a citizen oi the l'nited States, residing at Boston, in the county ol' Sull'ollc and State ol Massachusetts. have in 'ented new and usel'ul lmproyements in Electric Organ- Actions, ol' which *the Following is a specilication.

This invention relates to an electric organaction: and the object of the invention is to provide a sim le. crononial and quick-acting article ol' this clnrracter.

ln pipe-organs, where it is essential that an ell'er'tive electrically-controlled valve should be provided, my said improved action is particularly advantageous in View of the rapidity ol its operation, the econony of the action being due to the fact that but a small amount of current is necessary to bring about the operation of the same.

The said eleetric action involves in its organization a solenoid of novel Construction, but which is not claimed per se herein, one simple adaptation of which is illustrated `clearlvin the accompanying drawings, forming a part of this specilication, and which will be set forth in detail in the following description. ln said drawings I also illustrate one use to which the said action may be put; but l wish to st ate at this point that I do not limit n'yselt to this particular use, for the reason that the action may be ernployed equally well in other places in an organ, nor do I limit myself to the exact organization of electric action disclosed by said drawings and descriptionffor I may vary the sarne as to a number of details and like matters within the scope of my clans succeeding said descriptior.

liel'erring to the drawings, Figure 1 is a sectional elevation of a portion of a pipe-organ with an electric action illustrated in connection therewith and involving an enbodiment of my invention. Fig. 2 is a detail in elevation of the corc for the solenoid represented in the preeeding figure.

Like characters refer to like parts throughout the Views.

I will set forth the construction and relation of the parts rr-apresented in F ig. l, the same showing a portion of a pipe-organ. My improvedelectric action is, as will be gathered from the initial statements of my specification, ot' particular advantage in connection with the parts represented in said figure but, as previously intimated, such action may be used in conjunction with other rnechansin of the organ. Referring to said ligure, the numeral 5 denotes an ai1=chanber the air-pressur'e inflvhieh may be derived lTOlll anysuitable source. The chaniber 5 is in the nature of a main ehanber, an auxiliary or stop chamber being represented by 6 in said Fig. 1 and as communicating with said main or air charnber by a passage or windwy, as 7. In the stop or auxiliary chanrber 6 is situated an opening adapted to be closed by a flexible diaphragn 8', connected with one end of a stern or rod 9, said stern being end With a disk or equivalent valve, as 10. adapted to control the port 1 1 and the port 12 opening into the channel 13, which channel, it Will be perceived, extends froni the port 1 1 to a second port, as 14, closed at. its inner end by a flexible diaphragrn, as 15, on one end of a stern or rod 16. The rod 16 earries near its opposite end two valves, as 17 and 18, of a suitable nature, controlling the op posite ends of the port 19, opening at its inner end into the stop charnber 6 and at its outer end to the atin osphere. A channel, as 20, leads froni the port 19 to the pipe 21, and it will be apparent that upon the delivery of a blast of air of sufiicient intensity through the channel 20 into the pipe 21 the latterwill be caused to speak or sound. The opening which is closed by the flexible diaphragm 8 is the inner enlarged end of the channel or windway 22, the outer end of said channel opening into the charnber 23 below the air-charnber 5. In the bottorn of the chaniber 23 is threaded a nipple 24, the open under side of which is fiush with the lower surface of the casing containing the several charnbers. The nip-- ple communicates with the atnosphere, the top thereof being controlled by a valve, as 25, hereinafter more particularly described. Said valve is normally held seated against the upper open end of the nipple or pipe-section`24 by pressure of air thereagainst, as' will hereinafter appear, assisted by gravity in order to per-mit the direction of air froni the chaniber 5 in a manner hereinatter described into the channel or windway 22, where such air can act against the fiexible diaphragm 8 in order to press the same toward the right in Fig. l, thereby n'oving the stern in a corresponding direction, Whereby the valve 10 Will be caused to urcover the outer end of the port 1 I and be caused to sinultaneously close the port 12, leading to provided near its opposite IOO ' operatiorrofth'e valve 25, the diaphragm 8. is

' denoted in agenral way by 30, and it 'may whereby air can flow from the bhamber 6 into the atmosphere, -sotht the air which had passed into the chamber 6 from the chamber 5 by way of the windway 7 can enter the lower end of the chaiel 13 to travcr'se the latter and to enter the'port 14 to act against the diaphragm 15 a'press the same toward the left. When the diaphragm 15 is thus operated, the stem or rod 16 iscorrespondingly moved, so as to force the valve ;17 against the inner end of the port 19 and the valve 18 away ironiathe outer end of said port for preventingp'essure in the chamber 6 from entering said port 19 and for putting simultaneously the pi-pe 21 into communication with the atmosp here. v

The dupleX valve 25, aspreviusly stated,

is normally held seated against the nipple 24, and thisrelation meg' be'brought about simply by the air-pressure thereagainst augmented by the weight of said valve and thatof an armature, hereinafter described, connected therewith, or means, such as a spring, may be provided for aiding the air-blast and gravity in holding the valve against .the nipple 24. Upon' the energization of the elec trically-governedOperating member for the duplex valve 25, which member, as will hereinafteeapper, is a solenoid of peculiar constrtion, the valve'25 will be so moved as to uncover the open upper 'end of the nipple 24 and simultaneously, as will hereinafter ap pear, to cut off the flow of air from the chamber 5 to the channel or windway 22. The instant that'th valve is thus actuated to cut off the supply of air to the channel or wind-' way 22 'the air in' the latter can flow therefrom into the' chamber23 and from thence into the nipple or e' uivalent conduit 24 to the atmos here. W en the pressure `is re-- duced in t e channel or .windway 22 by the caused to collapse, thereby drawing the valve 10, through the intermediate rod or stem 9, inward and against the outer end of the port 11 and simultaneous'ly away-from' the port 12 to permit the air in the channel 13 and port 14 t escape to the -atmosphere by way of said port 12, whereby the diaph'agm 15 will be caused to 'Collapse in order to draw the valve 17, through the medium of the red 16, away from the inner end'of the port 19 andsmultaneously drawvthe valve 18 against the outerend of said 'port 19,

said port"l9,:the 'air passing" therefrom by way of the passage 20 'to'the pipe 21 to sound the same a i I The solenoid 'for Operating the valve 25 is be either simple or compound wound Conductors for supplying the solenoid30 withthe necessary electrc current su pliedby an electriegenerator' are denote each by 31.

that will hereinafter appear. While the s o- *lenoid is represented as being vertically disposed, this is not essential, as it may be horizontally or otherwise disposed. In like manner I do 'not limit myself to the disposition of any of :the other parts in any particular direction.

The solenoid is preferably, though not necessarily, wound on a metallic tube, as 33, which is ordinarily made from brass in order to decrease the iriction between the same and the core 34 of said solenoid. In order to materially increase the attracting power of the solenoid, the winding thereof is represented as surrounded by a soft iron casing, as

34', the rear or bottom head of which is sunk or let into the bottom'of the communicating chambers 5 and 6. .The core 34 of the solenoid isnade, preferably, of soft sheet-iron and is curled into the 'shape of a tube, so as i to constit'te, with the tube 33, a Conduit for v air. Said core has on itsrear or lower end a hook or bent projection 35, .connected with the valve 25. that the core for the solenoid is tubular and that the lower end of the same is se arated from the valve 25. Said core has a ee-lon-` itudinal motion in the tube 33. `It there-.

It will be evident, therefore,

ore follows' that in View of the tubular core and tube extendin through the solenoid air can pass throu h t valve 25 to ress the same solidly against its seat upon tlie upper tapered portion of the nipple 24, this being, as previously indicated, the normal relationof the parts.

e two tubular parts from l the chamber 5 r ownwardly to act against the It will be seen that what mightbe consi'd 7 ered the lower end of the tube 33 extends;

acts to hold the upper portion of the core away' rro'n the upper part of the iron caing and in this wayprevents any residual mag- 'netismthatmay be in said part of the iron easin when the latter is denergized from -retar ing the closure ofthe valve 25 against ;its seat upon' the upper side of thenipple `or pipe-seeton 24. Byvirtue also of this rela- `tion any residual magnetism' that may be in the lower part of the iron casing will` hate a IIO tendency'to'pull'thecore downward when the solenoid-circuit is broken, so as to cause the valve to seat lagainst the nipple 24.

'When' the solenoid-circuit'is closed, and this result is Secured through the action of an`organ-lgey,as customary in organ-actions, or in auf other desirab le way, the solenoid will be energized order toattractits core or r to i pull the same, in the present case upward, in opposition to the pressure of air against the valve 25, Whereby said Valve Will be moved away from the top of the nipple 24 and against the lower end 'of the tube 33 to thereby cut off communication between the chamher 5 and the windway or channel 22 and permit the reduction of air-pressure in said windway or channel 22. When such operatio'n takes place, the diaphragm 8 is caused to Collapse to therehy, through the agency of the ntervening parts, quickly move the valve 17 away from the inner end of the port 19 and to permit a blast of air to he supplied to the pipe 21 in the manner hereinbefore described. The moment that the solenoid-crcuit is opened the solenoid will be denergized in order to free the valve 25 from the action of the same, Wlw1'Gl) V the eomprcsscd air in the chamber 5, by passing through the tube 33 and the tube 34, will instantly force the valve 25 against the nipple 24 to resume the normal condition-%hat is, when the valve seats against the nipple the windway or channel 22 is put into communication With the cham-. her 5 in order to bring about the distension ol the flexible diaphragm 8 and through the intermediate parts the movement of the Valve 17 agai'st the inner end of the port 19 to stop the further supply ol' air to the pipe. 'l`herel`ore it will be understood that on the 'elosing ol' the solenoid-circuit the Valve 25 -t hermgainst is ohtained solely by the action 4.0

ol` the solenoid, Whihthe return motion of th( valve'is due toits weight plus that ol' tho- -or aterially :ssisted by the air-press'c on `said valvr, ltl lvtl hy the .'esidual agnets-"n in the lower part ol' thesoleoid.

'l`he pin or screw 25 is provided with two nuts 25 in threaded engagement therewith and between which the valve 2.3 is loosely. .n'a-united.
